摘要： A compound-input is provided for an electrically variable transmission for a motor vehicle. The compound-input electrically variable transmission has improved input gear ratios that allow the vehicle engine to be operated in its desired efficiency and/or performance range during both city and highway vehicle operation. Further, the multi-speed input electrically variable transmission provides an input brake without the need for a dedicated input brake clutch or braking mechanism and incorporates a reverse gear for reverse operation.

摘要： A multi-speed drive unit is provided for an electrically variable transmission having a variable-range output gear ratio for a motor vehicle. The variable-range output electrically variable transmission has improved final drive gear ratios that allow the motor to be operated in its desired efficiency and/or performance range during both city and highway vehicle operation. Further, the variable-range output electrically variable transmission allows for increased vehicle speeds during electric vehicle operation and provides for the use of the vehicle engine during reverse gear operation.

摘要： Methods and apparatus are provided for providing a torque boost in an electric motor system at low speeds. The electric motor system comprises an alternating current (AC) synchronous electric motor, an inverter and a controller. The inverter is coupled to the AC synchronous electric motor and provides electric control therefore. The controller is coupled to the inverter and provides operational control signals thereto for operation of the electric motor. The controller includes a torque command gain block which modifies a torque command to generate a boosted torque signal in response to a detected speed of the electric motor, the torque command modified to define the boosted torque signal defined in accordance with a torque dependent scaling factor calculated in response to the torque command.
摘要翻译：提供了用于在电动机系统中以低速提供转矩提升的方法和装置。电动机系统包括交流（AC）同步电动机，逆变器和控制器。逆变器耦合到交流同步电动机，因此提供电力控制。控制器耦合到逆变器，并提供用于电动机的操作的操作控制信号。所述控制器包括转矩指令增益块，所述转矩指令增益块根据所述电动机的检测速度修正转矩指令以产生升压转矩信号，所述转矩指令被修改以限定根据所计算出的与转矩相关的标度因子所定义的升压转矩信号响应扭矩指令。
